When receiving messages from external systems or sending messages to external systems, the protocol headers of the messages can be mapped to and from internal DittoHeaders.

That way the headers can be passed through Ditto or defined DittoHeaders like for example correlation-id may be mapped to a header used for message correlation in the external system.

A header mapping can be defined individually for every source and target of a connection. For examples of a definition see source header mapping and target header mapping.

Supported placeholders

The supported placeholders for header mapping are defined in the Placeholders - Scope: Connections section.
